Abstract (en)
[origin: EP0737965A1] An optical information recording medium which has a reflecting layer for optically reading information signals. The medium is composed of a plastic substrate. The substrate is colored with a dye so that the kind of information recorded on the medium can be visually confirmed at a glance whether the information is, for example, a game program, musical information, or other kinds of information. Usually, the optical system of a reader is affected and the reader cannot read data easily when such an impurity as the dye, etc., is mixed in the substrate. The influence on the optical system is eliminated because the particle size of the dye is reduced to 50 mu m. <IMAGE>
